These obstacles causes friction between water and rocks.This ultimately reduces the velocity of river water.The more roughness of the channel, the less the river`s velocity.

What three ways does a river erode it's channel?
The River's Velocity, Gradient, and Channel shape/roughness
What are the 3 factors that might influence how fast a stream would flow?
The velocity can be affected by many factors such as the narrower the river the faster the river will flow. There can also be debris in the river which will also affect the velocity and is the gradient is steeper then the river will also flow faster.
What affects friction in a river?
the gradient of the slope The channel roughness The amount and size of bed load
What is the velocity of a stream or a river at its local base level?
Velocity is the mean speed of flow over time (metres per second) measured either at apoint in a river channel or over a set distance.
What factor influence the shape of the land around river channel?
The factors are underlaying earth materials, the force of the water, and the amount of sand or water is also a factor. These are the three factors that influence the shape of the land around river channels.
Why does turbulence decrease downstream a river?
The channel roughness decreases because the water and little parts of rock in it will start to slowly smooth the surface under the water.
How does the gradient of a river affect its flow?
The gradient of a river is mostly flat or downhill which means that as the water flows it is affected by gravity. The steeper the gradient goes downhill, the more gravity will affect the water which will make the water flow faster (increases the velocity).
The technical term for a speed river?
it's velocity...it's velocity...
What does a rivers power to erode depend on?
A river's power to erode depends on the gradient, the volume and velocity, and the quantity of erosive burden. A river will normally move outwards on bends, deepening the farthest channel, and thus increasing the erosion on that bank.
What is river velocity?
it is the speed of the flow in a river
What is a channel in a river?
the bottom of a river
What a river flowes in?
A river channel
